@HAINQED YARN DOUBLING AND SPLITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 378,398, dated February 21, 1888.

Application filed April 21, 1887.

To aZZ 2071,0722, it may concern:

Be it known that I, SAMUEL M. J onNsoN, a citizen of the United States, residing at Saco, in the county of York and State of Maine, have invented a new and useful Improvement in Chained Yarn Doubling and Splitting Machines; and I do hereby declare that the following is a full, clear, and exact description of my invent-ion, reference being had to the drawings accompanying and forming a part of this specification.

My invention relates to the manipulation of chained yarns preparatory to dyeing or analogous treatment and the subsequent preparation of the yarns for transfer to beams or spools for use in the weaving of cloth. To premise, what isknown as chained yarns or yarns in the chain consists of any determined number of single yarns or threads in a condensed form and of any determined length. These chains are sometimes calledflong skeins. At determined points these chains are marked by the attachment of independent threads,usuually of a distinctive color. These marks are called leash marks. Each division thus marked is termed a leash. In this form the yarns are submitted to various treatment preparatory to being colored or bleached, the latest preliminary treatment being that of boil ing.

in the dyeing of chained yarns, in order to conduct the process with any degree of economy, it is essential that the chains should be doubled upon each other several times before being passed through the dyeing-vat. This is commonly done by hand and is a tedious and wasteful process, the chains often becoming twisted upon each other, rendering their subsequent separation difficnlt and to a great extent impossible.

The object of my invention is to expedite the dyeing of chained'yarns and their final preparation in form as continuous single chains preparatory to beaming or other forwarding processes.

o is a pin over which a strap, 0, passes. This strap supports the movable bar The stand 0 carries the raddle b and guideroll d. The stand D supports the draftroll stand is. This stand carries two drawing-rolls, So e and f, held in close contact by the weights h", attached to the levers i. The roll f carries a fast and a loose pulley, p and p, which receive motion through the belt in from any available source. The roll f is cut away at or near its center, and has a central bearing, is, on stand D, as shown in Fig. 9, as and for the purpose hereinaftershown.

The hanging frame E carries two triangular rolls, h and 71. mounted on shafts'h'and h. To these shafts are attached pulleys g and These pulleys are connected by the belt in. The shaft h of roll h carries a pulley, g",which is connected by means of the belt on with a pulley, g, on roll f.

FF are boxes to receive the yarns after doubling or splitting.

The office of the several parts of my improved doubling and splitting machine may be best understood from a description of the I00 processes of doubling and splitting by and with the use of the same.

The yarns in'the form of a chain, having leash-marks, substantially as hereinbefore set forth, are taken from the boilers in boxes or piles, each containing two leashes. Each pile is connected with its fellow, thus forming a continuous chain. These piles are placed on a platform between the friction-stand B and the raddle-stand C. The process of doubling of chains from two piles is shown in Figs. 7, 8, and 10, and is essentially the same when a greater number of piles are included in a single condensed or doubled chain. A bight of the chain from between two piles is passed over a peg of the raddle I), this operation being continued until all the piles are connected with the raddle, each chain being separated from its fellow by one or more pegs. This disposal of the chains is designed to secure their free passage from the piles and their distinct vertical passage in a sinuous course throughthefriction-barsotoandovertheguideroll B, where the several chains are united by a line called a looping-line, by which they are drawn forward and passed through a single mesh of the raddle b and beneath the guide-roll (Z to and between the drawing-rolls e and f, motion being communicated to these rolls through the belt m. The chains are drawn forward continuously and uniformly. By means of the looping-line the condensed chain is directed over the triangular roll h, said roll receiving motion through the belt m. From this roll, by its own gravity, it is deposited in the yarn box or boxes, as shown at A, Fig. 8. If desirable, these boxes,with contents, may be returned to the platform and the chain redoubled in manner and form as above set forth.

The office of the raddle b is to direct the chains and prevent their entanglement in their passage from the piles and distribute them evenly over and upon the friction-bars. These friction-bars are designed to retard the chain in its passage to the drawing-rolls and secure its uniform delivery, the amount of friction being controlled by the movable bar 0". The yarns, being now sufficiently condensed, are ready for passage through the dyeing-vats in an expeditious manner. After leaving the dyeing-vats, these condensed chains must be brought back to their original form of single chains to forward them for use in the manufacture of cloth. This (the process of splitting) is readily accomplished by the use of the same machinery, the raddle I) being removed from the frame B, or inverted, so that its back shall serve as a substitute for the movable friction-bar 0".

The splitting process is illustrated in Figs. 1, 2, 4, 5, and 6, and is substantially as follows: The doubled yarns are taken from the dyeing or bleaching vats in boxes or piles and placed on the platform, as before described. By the use of the looping-line the condensed chain is passed ,sinuonsly over the friction.- bars and guide-roll, as shown in Fig. ,1 The doubled chain is then separated into its snr gle parts or chains, which are separately conducted through individual meshes of the raddle b, and thence through and between the drawing rolls e and f, the motion of which draws the separated chain forward. These separated chains are then passed over the triangular roll h, a part being allowed to fall over said roll, while other chains are carried forward over the roll 7L2, over which they fall. These chains are received in boxesFF. The chains are received in these boxes on. a small board called a packing-board, from whlch they are removed from time to time and placed in order in the several boxes in such a manner as to secure their free delivery when required.

The friction-bar 0 has a vertical movement in the slot 0 By its elevation or depression the tension of the chains is regulated. In splitting, this tension is such that the strain on the chains consequent on the draft of the drawing-rolls, together with the spread of the chains from the guide-roll B to the raddle b, is sufficient to separate the chains as they advance and secure their perfect separation and even delivery to the drawing-rolls. The raddle I), being only of use in the process of doubling, is removed in the process of splitting, the friction-bar 0 taking its place. This raddle b may, however, be made a permanent attachment to the frame, and when inverted serve as a movable friction-bar in the process of splitting.

The drawing-roll f is supported at or near the center by the bearing k. ment prevents the springing of the roll during the passage of heavy chains, andthe interstice above the bearing k allows of the ready introduction of the chained yarns without necessitating the removal of the weights from the roll 6.

The triangular rolls are an old device for drawing forward loose yarns, and are not claimed as my invention; neither is the process of depositing the yarns on small packing boards claimed as new; neither is the centrally-journaled roll claimed as my inven tion.
